Not too long ago, Unix systems replaced seek() with the lseek(), and were able to handle longer offsets even though they were 16-bit machines. The word width of your CPU in no way limits the width of words upon which you can perform arithmetic. The new 48-bit field is not using compiler types wider than 32 bits for its implementation. They could use "long long", but I suppose that's less portable.
